is it true what i heard, that wizard supports usb hosting? what i understand it means, it would be pluging usb drive to wizard usb through some kind of usb mini adaptor and accessing this drive through wizard? is it true? any special cable required or just mini 2 mini usb?
Not true. Search the forum.
thanks hanmin i did, just wanted do make sure.
i got confused by the usb host drivers floating around...
so should i understand these ar ment for other then wizard wm5 devices, or is it generally not true?
Good if you can point out where you get to know about this.. usb host drivers.
As far as I know, it is not true for all current devices discussed in this forum. If it were to be true, I think I would have known it as it is a rather big 'feature'.
this url http://www.deje.gmxhome.de/software.html was mentioned by someone asking similar question in this thread
http://forum.xda-developers.com/showthread.php?t=270117&highlight=usb+host+wizard
if you scroll down the page you will read
"This is a driver which enables you to use USB mass storage devices (HD, multimedia Reader, digital camera) with your USB host enabled PocketPC."
that's exactly what i'm unsure of, are there any usb host enabled PocketPCs?
in addition here's a place where i first read it's possible
http://pdaclub.pl/dl/file_view.php?f_cat=92&sortby=t&sort=asc&f_id=530
unfortunately it's in polish, so no use for you guys. It states that
"WM 2003 SE original built in drivers allow you to use most generic usb storage, digital cameras, and even usb keyboards..." this site doesn't give any details about authors homepage, but mentiones that its the same guy who did MPointer (usb mouse plugged to pda)
don't really know what to think about it... enlight me
Interesting... it seems to be working on some PDAs...

Hmm.. you can try the suggestion here
http://pocketpcmag.com/forum/topic.asp?TOPIC_ID=13738
But, I still think the current units discussed in this entire forum can't do it.
Thats what i ment. there are rumors it could work... but until i'm sure, i think i'll pass... i'm a bit affraid to play with power. Wouldn't pluginn a HDD to a device the way i'm unsure of... would'nt it be dangerous for my wizard? i'm a bit worried, because i already lost one of these toys due to electricity... http://forum.xda-developers.com/showthread.php?t=281932
Ok, did some seaches, and this thread is interesting
http://forum.xda-developers.com/showthread.php?t=250344&highlight=
At the end of the last post, someone mentioned that all HTC devices has a 3.7v battery which would not able to generate a 5v required for any USB devices. This fact seems to be true enough, in a electrical point of view. Theoritically, it is possible to generate a higher DC voltage via a DC source, however, it would take up relatively large expensive real estate of the motherboard. So, unless HTC has a very good reason, requiring them to get a 5V from a 3.7V (eg for some fussy components), HTC shouldn't have any form of DC voltage doubler in the unit. So, consider the voltage wise, you are out of luck.

Yes that is true, but they are also saying that the processor of the wizard can act as an usb host. So maybe it should work with an external powersource, aka USB Power Injector.
...which leads us back to Zeno's drivers that require a USB power injector...

Hells bells I got it to work at last.
A lot of you have been experimenting with usb hubbs and can only get athena to see 2 ports on a 4 port hubb.
WELL I can now see 3 ports.
Running a usb 104 keys keyboard
usb mouse
kingston datatraveller 2.0 GB memory stick (sees it as a "Hard Drive")
I now run it on tiniest vga screen hooked up to an LCD 19inch (or wifes 22 inch wide) with above connected - running dataviz docs to go which gives me desktop word excel powerpoint pdf as well as Handbase (access like program)
FANTASTIC
The trick after losts of experiments is the following
In the HTC 4 in 1 cable usb slot I plugged a digitech micro usb hub (in other words a device which has 1 usb port connector on the LHS and 4 usb ports on the RHS all in one solid plastic block ie no cables
I cannot find this hub again as I have had it for some time but on the net i found this one from china which appears simmiliar and hopefully will do the trick in that it will see 3 out of the 4 ports (sees any 3 ports) but not the fourth one !!!!
I think the ability to see 3 ports instead of 2 is that it must be usb 1 (these are usb 2.0 devices below) and it must be a solid block with no cables - all the others I tried never got past 2 ports.
Maybe the usb 2.0 solid blocks below will also work - maybe the clincher is losing the cable and haveing the solid block
All usb hubs with the cables (even self powered ones) will only see 2 ports !!!
Hell I am trying
Got my setup to work like a bomb.
Will also see my integral 8 in 1 sd card reader and read my memort sticks and sdhc cards (again the card reader is one of those solid blocks with a usb port - no cables)
(Note : You have to remove the memory stick to plug in sd card reader and will only see one card at a time)
See items below
I have not tried these but my one is like these below
Happy computing
So for me I guess I will pass on the shift - I already have one at a hell of a lot bucks less.
Found a Belkin one as well model F5U018

Wow, looks like you made progress so thanks. I was wondering if you had a external 2.5" HDD caddy (USB, self - battery or mains powered) you could try for us?
I've started three threads on mutliple forums to get to the bottom of why the 4 in 1 cable isn't cuttting it with USB devices and so far the excuse is that it dosn't have the umph to power power hungry USB kit like a spinning Ext HDD Caddy! But your setup might work especially if the Caddy has it's own power source, which mine has in the form of mains or lithium battery pack.
Any way if it's not to much trouble your help would be much appreciated by myself and others following this issue.
Thanks Optical10

Am I right in thinking that the USB Host hardware on the Athena is USB 2.0 but that WM6 is only capable of seeing it as 1.1? Thought I read this somewhere......anyway just a thought but maybe the OS can tell the difference between a solid state disk and a platter disk; thus no matter how much power you throw at it it won't work. Either that or it simply won't read above a certain capacity. Whichever is true I think it's safe to say that the external HDD debate is a dead duck: USB host has never purported to read full-on hard disks, only thumb drives and HIDs: there is clearly a reason for this.
My old toshiba e750 from 4 years ago had usb host capability. It could see all 20gig of my selfpowered X-drive.

Bizarre. What os did that run? I thought USB host support only came out with WM5
PPC 2003 SE, I was running a 4port hub and could use a usb gps, the 20gig x-drive, usb keyboard, and mouse. Only the x-drive needed external power, the other attachments worked just fine. Strange that current devices cannot even to that.
Hi Guys
I am back again.
I dont have a usb caddy but I have a usb (self powered) HDD cage that takes a 120GB 3.5in hdd.
I will try this on moinday evening when back home and report back
Hi
I am battling to see the HDD
Will have to try a smaller size.
Found a way to get rid of office mobile s??t once and for all.
Go to Docs to go folder and copy the 5 programs to a new directory
wordtogo, exceltogo, powerpointtogo, ziptogo and pdftogo.
Then rename them as follows:
wordtogo.exe to pword.exe
exceltogo.exe tp pxl.exe
powerpointtogo.exe to ppt.exe
ziptogo.exe to zipview.exe
pdftogo.exe to (using pk 3.0 touch version of rom) to ppc_adobereaderle.exe
then copy these 5 programs to c:\windows
the pword + pxl + ppt files will lie alongside their rom conterparts but the ram versins will always boot first.
zipview and ppc_adovereaderle will overwrite their ram counterparts.
Now whenever you see an attachement or anything it will always open docs to go equivalents and the office mobile link files (.lnk) in rom will call the ram versions which are the docs to go programs
Voila and now you have proper word excel powerpoint and pdf ???? as well as zip programs
cheers

hi
i think u r right
wm6 seems to see all devices as usb 1.1
No, I don't think WM6 can only see it as USB 1.o Some winmo devices are having USB 2.0.
See this for example:
http://www.sideshowdevices.com/i-mate-ultimate-wm6-phones-with-vista-sideshow-support
I think it is the software driver used, but I'm not competely sure. It cannot be due to hardware because WM5torage allows the PC to see Athena as USB2.0 harddisk. May be I'm not talking sense, but anyway.

usb client and usb host are different. wm6 certainly supposts usb client, though until recently even this aspect was only usb 1.1 in HTC devices, certainly,
So
Lets see if I get this correct (dumb ole me)
Usb client services on Athena couldbe usb 2.0
usb hpst services could be 1.1
Surely then this could be thew driver used.
If so can this be changed in the PK 3.0 black rom ????
Maybe ask olipro crowd ????

You're right.
There's no doubt in my mind that WM6 does support USB 2.0. The technical savvy might be able to port the right driver over to Athena to test.
Has anyone ever tried this on our devices?
http://forum.xda-developers.com/showthread.php?t=480899
If so please post what happened, whether successful or not..
According to what I've read all that is needed is a Processor that is compatible with USB-Host features (which the OMAP850 is apparently capable of) and an injected power supply if your battery cannot supply 5v (as our batteries only output 3.7v)
I'd test it myself but I dont have a means of injecting 5v yet.. apparently one may use a "Y" cable that some external 2.5" drives are supplied with

Well i have seen this just not found the time to play with it looks very interesting but while i was searching for a cable i found this article on how to make your own
http://tabletblog.com/2006/01/usb-power-injector-for-usb-host-mode.html
Just had to add this one so simple to build i can't wait to try this build so easy
http://tabletblog.com/2006/01/usb-power-injector-2.html
Looks interesting.. I need some free time to go out and buy some usb's and build.. but I had a "Y" cable and a 220v to USB adaptor that I planned to use, which should do the trick.. I've found the adaptor, just cant find the cable..
Any way good luck with the build.. Let us know if it works
And please be careful Wapvirus .. You're very brave to try this when you've just got your new device TEST Volts and Amps thoroughly before testing on device
I did try this but nothing happened. i might be doing something wrong but for now i must say that this does not work. (wm6.5 and y cable from usb hdd)

Thanx for your response.. so what did you use to test? the hard drive? tried other devices like flash drive, mouse, card reader, etc?
Can someone explain why the MHL/HDMI adapter on the SGS2/Infuse needs to be powered unlike the HDMI/Mini HDMI in the Samsung Droid Charge? Why the difference?
Short answer is that its a Samsung decision for it to require power (the power is to charge the phone, not the adapter/cable). Presumably they made this decision to prevent the inevitable "battery life sucks" comments from muppets who don't realise outputting HD content is battery intensive. Too bad more people are more unhappy about the restriction eh?
Other MHL cables should work without needing a charger connected (its a standard connection)... or at least when they're available they should work, so it may be possible to work around this by using an HTC MHL cable for example.
http://www.youtube.com/watch?v=8xeQ99FW74c&sns=em
YT video that touches on this.
Is there another type of cable known to work that does not have to have the power requirement?
I don't care if the device cannot be changed, especially as I don't have (and won't buy a new) MHL enabled television set. In fact, I don't think that there are any MHL enabled T.V sets out there, or have I misunderstood the MHL/HDMI specs ? (wikipedia is not very useful on MHL for the moment, hence the confusion).
Regards.
Ok guys and girls, this thread is for hardware hacks. The reason for creating this thread is initially to address two scenarios.
Bricked device
HBOOT/Recovery Mismatch
And the goal is to produce two things.
JTAG pinouts for the flyer
Build a low cost emergency charger that can be used to recharge a completely flat flyer battery in order to recover from the unbootable state.
A bootstrap battery pack to be used as an alternative to #2, giving enough power to flash the correct recovery and charge normally.
I will be working on item 2 in the two lists first ( and number 3 on the second list) , because it's both a more common thing to encounter and because I need equipment that I don't currently have for number 1.
Did you search the DEV section before creating this thread? I swore I seen a couple of threads talking about this.
Another nice thread Globatron, do you think you could give a short description about what a Jtag/ort jtag unit is for people that aren't familiar? Too avoid those repetitive questions..
Sent from my HTC Flyer.
Sure, I'll do that.
Here's a visual tear-down of the Flyer from TechRepublic for those that have never opened it up.
http://www.techrepublic.com/photos/...3?seq=2&tag=content;siu-container#photo-frame
Man. This is really not like tearing a Laptop or a PC. After such tear up i don´t think i could get it all back together. All parts ant connections are so small, i don´t even see what part to connect to JTAG pins. And yes the screwdriver a shape of a star
Ok, so for the charger design there are two basic options and one extended option:
USB powered
Mains brick powered
Both, mains power taking priority if both are connected
Can I get a feeling of what people would like to see in terms of supply? I will not be using the flyer charger as a power source due to the problem of obtaining the custom connector to mount on a pcb but I can do a wide-rage input to cover ~ 5V - 28V.
The booster battery method is simpler. I'll have a prototype done as soon as I get a delivery of the appropriate connectors.
A couple more software procedures and then it's back to hardware.
Hubless USB OTG is added to the list.
Happy New Dragons Year Everyone!
I made some posts in riff box forums. I've visited jtag repair services and no one could help me. And i found that jtagers have no interest of flyer
Be more specific

Yes I want that.!!!!!!! Where is the 'How do'
PLEASE!!!!!!!
There is no how to, you can't do it. That's why he is investigating. The Flyer as designed supplies less than 80ma of power to the micro USB port, not even enough for most small thumb drives.
I'm going for a long trip and unable to bring my laptop, so I need to do everything from my RAZR. I bought a USB OTG cable and a USB Y-cable thinking it would be the final solution.
The main problem with the card readers as some of the USB sticks is that they all want >100mA and RAZR reports being unable to supply that amperage. You can debug this using USB Host Controller and enabling the 'DMesg display mode'.
Simple permanent solution:
buy a cheap unpowered usb hub. Since weight and space are my main concerns I cannot travel with powered hubs.
Complicated temporary solution, requiring root:
Check the dmesg output from the above application or by doing a tail -f /var/log/dmesg in terminal and see what port is being reported as underpowered. Most of the time it will be this: "usb 3-1: rejected 1 configuration due to insufficient available usb power". Of course that's not true since the power is provided by an external brick capable of supplying at least 1 amp.
You have several ways of doing this, I'm using root explorer as an example. Go into /sys/bus/usb/devices/3-1/ , click on the bConfigurationValue file, select 'Text Editor' from the prompt, type "1" into the editor, save and exit.
You will have to do this every time you plug something in so you might make it into a script, something like "echo 1>/sys/bus/usb/devices/3-1/bConfigurationValue".
Other issues: I'm taking two cameras with me, a Canon SX230HS and a Nikon D7000. The problem with new cameras is that they have given up on the Mass Storage protocol and switched completely to PTP (Picture Transfer Protocol).
Simple solution: use an SD Card reader to transfer photos. Use USB OTG Helper to help you with mounting, it's a free one-click solution.
Complicated solution: for Canon I'm using RawDroid. For Nikon I'm using DslrDashboard.
If you can afford it, PhotoMate should also work.
Oh, this should go into the Accessory forum, or maybe not even on this forum, but I was able to ditch the camera chargers (two wall bricks + two chargers) by buying a PIXO C-USB charger. It's one of those universal LiPo chargers with spring contacts. You can plug it into a USB port or USB charger and you can charge 1 cell or 2-cell LiIon/LiPo packs or AA/AAA batteries.
I am still looking for an efficient 2xAA/AAA -> USB high current supply for complete portability, but I might just build one myself. The reason is that you will find batteries everywhere but less so publicly available power sockets.
Hmm, I think that for a cheap USB power, you could use one of those smartphone battery backup usb batteries. The problem I see with AA or AAA is that they are less efficient due the extra space they need because of the packaging of each battery, and the materials (NIMH vs Lithium)
Also, taken from this thread: http://forum.xda-developers.com/showthread.php?t=1349038
You need a powered hub in order for the RAZR to accept it, and I think this is a kernel issue, and cannot be modified just with root (Because of the locked bootloader).
I think that probably what you need, as you stated before, an external source of power, and probably something like this powered usb hub:
http://www.ebay.com/itm/Black-Samsu...o-USB-Host-OTG-HUB-CARD-READER-/160921077532?
It needs to be powered in order for it to work with our RAZR.
Have a look at the entire thread that I posted before, I think it could be helpful.
I am already on my long trip and the non powered usb hub worked perfectly. I already explained how you can 'fool' the kernel into thinking it has enough power, this is a non-issue. The thing with AA/AAA is not density but it is they are readily available in remote areas of the world where there is no power.
I already tested one AA/usb power supply I had for overload and magic smoke came out.
It worked for me. However it depends on how the hub and charger are connected. I had to connect the hub between the female plug of the otg-cable (a y-cable) and the usb stick and the charger to the male otg-cable plug. Connecting the charger directly to the hub didn't work.
